Dark Divide Trail Races

The Dark Divide Trail Races are a series of trail events held in September 2026 in the Dark Divide Roadless Area within the Central Washington Cascades and Gifford-Pinchot National Forest. The races use Cispus Learning Center near Randle, WA for race headquarters and the start/finish area. Cispus facilities include showers, a kitchen, bunkhouses, and parking. Beds at Cispus may be reserved on UltraSignup for a fee.

Distances offered:

  • 100 Mile Endurance Run (48 hour cutoff)
  • 100K point to point
  • 50K
  • 14 Mile Fun Run

Course terrain includes steep, technical trails, alpine ridges, serrated peaks, waterfalls, subalpine meadows, old-growth temperate rainforest, and remote valleys. The 100K course highlights alpine ridges, technical ridge running, and several classic segments of the 100 mile route. The Dark Divide 100 Mile Endurance Run is a qualifier for the Hardrock 100.

The event introduces one-time cash prizes for specified performance and multi-finish milestones, including awards for the first sub-24 hour female finish and first sub-20 hour male and non-binary finishes, and larger awards for the first five-time finishers in each gender category. The race operates under a Special Use Permit through the Gifford-Pinchot National Forest. Portions of proceeds will benefit local organizations including Silver Star Search & Rescue, the All Play program, and the White Pass Scenic Byway.
